Ive installed VoodooHDA 2.7.2 with pref pane on Samsung R590. Sound works but with Larsen effect. I would be very happy if somone could point a way for repairing the Larsen effect! I don't know how to fix those problems:

Thanks Narandill, this is excellent! I was about to deinstall VoodoHDA and give up on this until the next verion of VoodoHDA is available.

However it is not a complete solution, at least not on my Samsung RF710. Narandill, please check if you really can use your mic, especially the built in mic. Try in in an application, such as iChat or skype.

This is what I get in the Samsung RF710:

The change in iGain from 90 to 0 is having the very welcome effect that the Larsen effect starts much later. Now the volume can be set to a level where you can actually use the built in speakers. Nevertheless the mic is still always on and directly outputting to the speakers. Full volume gives you Larsen.

A Workaround is to plug in an external mic and direct it away from the speakers, now almost no Larsen, even at high volume.

And/or plug in a headset, so the mic doesn't hear the speakers output.

As long as the direct connection mic -> speakers is not solved, it would be great to have a setting to switch off the mic completely (plugging in a cut-off plug or a mic is not very practical if on the road with the notebook). Adding Mic=0 doesn't switch it off. Is there such a setting?

Make sure, that you are doing clean & fresh install of VoodooHDA. Delete all previous voodoohda editions, restore original applehda.kext. I used the VoodooHDA 2.7.2 installer (pkg), then I'm imported hacked VoodooHda.kext by Kext Helper.

Here is an output from diabolik web site as The King suggests. FYI I am also including an AppleHDA zip that if you apply works, except for Mic. At least you get the sound. Hope you can help. This is really a big major issue for many of us.Artimess

The output of what i did; first time after installion of kext i will get a kernel panic, but when i restart the machine a few times it will eventually boot up.I've tried doing that with a different kexts (even voodoohda 2.7.2) but it won't work, sometimes i get larsen effect, but sound doesn't work. And i can't let mac go to sleep because the screen turns black but the computer is still working, and i will have to restart the computer via the power button.
